If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Could you please provide information on the type of buffer to use for isolating proteins from insect tissue in a way that will preserve the carbonylation for the MAK094-1KT Protein Carbonyl Content Assay Kit? Additionally, do you anticipate any adverse effects from Decolor paint pens on the cuticle of the insect tissue sample?
1 answer-
It is recommended to homogenize cells using mechanical cell disruption in water only, as common buffer components can interfere with the protein carbonyl content of the sample. If the protein is very dilute, it can be concentrated using a 10 kDa spin filter. For the assay, it is advised to use 100 µL of sample containing approximately 0.5-2 mg protein and include a reagent background control by using 100 µL of dH2O alone. Regarding the impact of xylenes on this assay, it would need to be confirmed empirically.
